Justification:
Secondary poisoning with rodent poison (Brodifacoum) in the year 2001 led to a decline in the popualtion of about 87%, relative to the population size in 1999. The causes of this decline have ceased and future population increases are expected.

Predation by rats was speculated to be a threat in the 1990s. Eradication of rats using Brodifacoum poisoning was associated with an 87% population decline in this species between 1999 and 2001. The successful completion of the rodent eradication means that neither of these threats remain. Currently no active threats are known. Large-scale agro-industry farming and plantations caused some habitat degradation in the past.
